GEORGE I4. PHELPS, OF CHICAGO, ILLINOIS, ASSIGNOR TO INTERNATIONAL HARVESTER COMPANY 0F NEW JERSEY, A CORPORATION OF NEW JERSEY.

conn HUSKER AND snnnnnnn Maaate.

all whom t may concern:

Be it known `that I, GEORGE L. PHELPs, a `citizen of thelUnitedy States, residing vat Chicago, in the county of Cook and State of es Illinois, have invented certain new and use ful Improvements in Corn Huskers yand Shredders, of which the following is a full, clear, and exact specification.

My invention @relates to corn huskers and shredders,` and consists in improved means for mounting and controlling the movement of the snapping rollers and in means whereby motion is transmitted from the shredder cylinder to other operative parts of the machine. The object of my 'invention is to simplify the construction of the machine and make it more eflicient in operation. yThese objects are attainedbv means of mechanism, one embodiment ofwhichis illustrated in `the accompanying drawings, in which-Vv Figure 1 is a' top plan view of part of acorn husking'and shredding machinehaving invention embodied in its construction; Fig. 2 is a sidewelevation of Fig. 1; y Fig. 43 is a partial plan View of a spreader head, l. y

Fig. 4 is 'an end'j ,view, partly in section, of Fig. 3;

Fig. 5 is a side elevation of Fig; 1 from the opposite side of the -machine as seen in `Fig.2;and 11 Figli is a `detail part of the snapping roll mechanism. y

The same reference numerals designate 5 like parts throughout the several views.

r1 represents the frame of the machine having a base sill member 2, an upper longitudinally disposed frame member 3 connected thereto by means of vertically disposed frame members 4. 5 represents an intermediate longitudinally disposed frame member secured to thevertical members 4, and 6 represents a shortvertical frame mem ber having its opposite ends secured to the members 3 and 5. 7 represents a feed shaft journaled in bearings 8 secured `to the frame `members 3 upon opposite sides of the machine and carrying a feed apron 9. 10 represents the lower snapping roll having its reduced ends journaled in bearing boxes 11 n carried by base members 12 secured to opposite sides of the frame structure, and 13 represents the upper coacting snapping roll journaledy in bearing boxes 14 forming part-V 55 of swinging yoke members 15 having sleeves Specification of Letters Patent.

16 that turn about the aXis of the feed shaft 7, the sleeves being connected with .the bearing boxes 14 by means of threaded rods 17, whereby Vthe distance between the axis of roller 13 and feed shaft 7 may be properly regulated.

The bearing boxes 14 are provided with cupshaped members 1S at their upper sides, 1n ,which are seated the lower ends of two `coiled compression springs 19 and 20, the spring 20 belng within spring 19, the springs Y having unequal force for the purpose of eX# erting variable pressure upon the Vupper roller 1n its operation. 21 represents a pressure regulating link having a hooked lower end received by an opening in the bearing box member 11and extending upward within the springs is provided with a washer 22 and adjusting nuts 23. 24 represents shredding cylinder shaft journaled in rear of the snapping rollers in bearing boxes 25 Vcarried by the base member 12, and 26`a spreader shaft j'ournaled abovey the-feed 5 shaft 7 in bearing boxes 27: carried by bracket 4members 28 that areintegral with v the base members 12` the spreader compris.

ing spool members 29 lthat receive between them alband cutting disk 30, and 31 represents voppositely disposed spirally" arranged v stalk spreading ribs secured tof-thespools upon opposite. sides of the bandy cuttingdisk. 32 represents a driving shaft for the husking rolls (not shown) ,and33 a driving shaft:`

for'they ear agitator (not shown). 34 represents a fly wheel secured to one end of the shredder cylinder shaft, and 35 a driving pulley secured adjacent thereto.

Motion is transmitted to the various shafts from the shredder cylinder shaft by means of a pinion 36 secured to said shaft upon the opposite end from the y wheel, the pinion meshing with a gear wheel 37 secured to the end of the lower snapping roller, and 38 represents a sprocket wheel secured to the same shaft inside of the gear wheel; 39 a sprocket Wheel secured to the end of the feed shaft 7; 40 a sprocket wheel secured to the end of shaft 32, and 41 a sprocket chain operatively connecting the three sprocket wheels. 42 represents a sprocket wheel secured to the feed shaft 7 inside of the wheel 39; 43 va sprocket wheel secured to the end of shaft 33, and 44 a sprocket chain operatively connecting the two sprocket wheels.A

iio

ing` roller,

placement, and the swinging yoke members 15 will maintain the driving gears 45 and 46v upon the feed shaft 7,. and the upper snapping roller 13 inL proper mesh', and the rods 17 may be manipulated in a manner to regu-late `the degreeY of engagement of the teeth of the two gear Wheels, and said degree will not. change as the ,upper rollery rises or falls in the operation of the machine. The springs 19y and 2O are*V made of different lengths and force so asr to exert a relatively small resistance in opposing an initial rising movement ofthe upper snappingV roller through apredetermined distance, which I prefer to be approximately 9i, anda much greater resistanceV as that distanceincreases.

While I have in this application de scribed one form which my invention may assume 'in practice, it is, of course, to be understood that the form shown herein is susceptible of modification without departingfrom the spirity of the invention.

SWhat I claim as mvinvention, and desire tofy secure by Letters Patent,is :i

I. In a corn handling machine, thev combination of coactingupper andlower snapping rollers, the upper roller being permitted a rising and falling movement,.ay feed shaft, means for" driving said shaft and rollers,fand swinging extensible supporting @means directly connecting said feed shaft with the upper roller.

Go'pi'es'of this vpatent mayl' be obtained for are all journaled in bearingsv forming a part of the base membei's'IQ, and" are, therefore, securely held against dis upper roller,

r2. In' a corn husking and shredding inachine, in combination, coacting upper and l lower's'nappin-g rollersfrotatable in opposite diifectionsg-'tho upper roller being' springpressed and permitted a rising and falling movement, a kfeed shaft, means for driving Vsaid feed shaft and the lower roller in the same direction, extensible swinging yokes directly .connecting saidfeed shaft with the upper roller, and a driving gear connection between said roller and shaft.

8, In a corn husking and shredding machine, in combination, coacting upper and lower snapping rollers rotatablein opposite directions, the upper roller being permitted a rising; and falling movement, a feed shaft, Y

means for driving said feedl shaft and the lower roller in the 'same direction, swinging yokes adjustable in length1 andconnecting said-shaft` with the upper roller, and radriving gear connectionv between said roller and shaft.`

4.y In a corn husking and shredding machine,vinv combination, upper `and lower coacting snapping rollers rotatable iny opposite directions, the upper roller being permitted a rising yand falling movement, linkr connections, between ythe bearing' boxes of the two rollers, and two springs, one within thek other, encircling the body yofeach link and operative toiresist a rising movement of said one of said springs being inoperative during the initial rising movement of said roller. .Y

In testimony whereof I affix my signature, in the presence of two witnesses.
